测试环境
Anolis OS8.6
Virtual Box，4 vCPU, 8G RAM, 50 vDisk。安装时删除/home，SWAP分区，全部空间给/目录。
目标是部署OpenStack All-In-One模式，控制节点+计算节点+存储节点在一台机器实现。
系统配置
常用工具
dnf install -y tar git
优化SSH
vi /etc/ssh/sshd_config
UseDNS no
systemctl restart sshd
关闭selinux
sed -i ‘s#SELINUX=enforcing#SELINUX=permissive#g’ /etc/selinux/config
关闭防火墙
systemctl disable --now firewalld
systemctl stop firewalld
systemctl status firewalld
设置主机名，配置hosts文件
hostnamectl set-hostname node1
cat << EOF >> /etc/hosts
192.168.31.115 node1
EOF
设置免密登录
ssh-keygen
ssh-copy-id node1
重启系统
system reboot
升级Python3
yum install -y python39-pip python39-devel python39
rm -f /etc/alternatives/pip3
ln -s /usr/bin/pip3.9 /etc/alternatives/pip3
rm -f /etc/alternatives/python3
ln -s /usr/bin/python3.9 /etc/alternatives/python3
安装docker
wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum clean all
yum makecache
yum install -y docker-ce
指定docker加速器，阿里云申请免费
mkdir -p /etc/docker
tee /etc/docker/daemon.json << ‘EOF’
{
“registry-mirrors”: [“https://xxx.mirror.aliyuncs.com”]
}
EOF
systemctl daemon-reload
#启动docker服务
systemctl start docker
systemctl enable docker
systemctl status docker
docker info
docker --version
安装Python docker模块
pip3 install “docker<5.0.0”
安装ansible
更换pip国内源，加速pip下载安装
mkdir ~/.pip
vi ~/.pip/pip.conf
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host = pypi.tuna.tsinghua.edu.cn
pip3 install --upgrade pip
pip3 install setuptools-rust
pip3 install ansible==2.9.27
ansible --version
优化ansible
mkdir /etc/ansible
vi /etc/ansible/ansible.cfg
[defaults]
host_key_checking=False
pipelining=True
forks=100
ansible-config view
安装kolla-ansible
安装kolla-ansible需要的依赖
yum install -y python3-devel libffi-devel gcc openssl-devel python3-libselinux
安装kolla-ansible
版本信息 https://docs.openstack.org/releasenotes/kolla-ansible/
pip3 install pbr
pip3 install kolla-ansible==9.3.2
部署OpenStack
#创建kolla-ansible配置文件目录
mkdir /etc/kolla
chown $USER:$USER /etc/kolla
#配置文件
cp /usr/local/share/kolla-ansible/etc_examples/kolla/globals.yml /etc/kolla/
cp /usr/local/share/kolla-ansible/etc_examples/kolla/passwords.yml /etc/kolla/
cp /usr/local/share/kolla-ansible/ansible/inventory/all-in-one /etc/kolla/
sed -i ‘s#localhost ansible_connection=local#node1 ansible_python_interpreter=/usr/bin/python3#g’ /etc/kolla/all-in-one
生成密码
kolla-genpwd

服务验证
安装openstack客户端
pip3 install python-openstackclient
source /etc/kolla/admin-openrc.sh
